Abstract

The invention discloses a network slice authentication method, a corresponding device, a system and a medium, which are used for solving the authentication problem of UE accessing the network slice ina mobile communication network. The method comprises the following steps: acquiring a network slice authentication vector corresponding to the user network slice identification information of the user terminal from a network authentication entity; and authenticating with the user terminal according to the network slice authentication vector. A method for authenticate network slice in that invention and corresponding device, When the UE attaches to the mobile communication network and further accesses the network slice to receive the service provided based on the network slice, the system andthe medium effectively meet the dynamic deployment characteristics of the network slice, so that the attachment process meets the authentication requirements of the UE accessing the network slice.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an authentication method for network slicing and a corresponding device, system and medium. Background technique [0002] The 5G (fifth generation mobile communication technology) network architecture will introduce new IT technologies, such as Network Function Virtualization (NFV, Network Function Virtualization). In 3 / 4G networks, the protection of functional network elements largely depends on the security isolation of physical devices. In the 5G network, due to the deployment of NFV technology, some functional network elements are deployed on the cloud infrastructure in the form of virtual functional network elements. A virtual core network constructed based on network service requirements is called a network slice, and a network slice constitutes a virtual core network to provide mobile network access services for a group of specific user terminals (UEs). A typi...
